Hi!
I just go some ML bulbs, its called ML 100W E E27. They got mercury vapor in them. The shop assistent said that this is like hps. Its that true, i can use this for growing?
Thank for your answer!
Umm, i dont want to buy a transformer for the bulb. I dont have money to buy bulbs, and where i live are very expensive.
10 inches and 2 pc cooling fans are okay? And the 2 bulbs should be above the plant or beside the plant?
